To all whom it may concern:

Be it known that I, FRANCIS MEISEL, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Bed-and-Platen Printing-Press and Inking Mechanism Therefor, of which the following is a specification.

My invention relates to improvements in bed and platen printing presses and inking mechanism therefor; the principal objects being to provide for running at'a high rate of speed, using type forms with safety; for efficiently applying ink to the type forms; also to provide for connecting the inking mechanism with the apparatus for operating the press in such a manner that the inking mechanism will operate constantly independently of the position of the bed or beds.

Further objects and advantages of the invention will appear below.

Reference is to be had to the accompanying drawings which constitute part of this specification, in which Figure l is a side elevation of a bed and platen printing press showing one form of my invention applied thereto. Fig. 2 is an enlarged view of certain parts of the same, showing additional details of construction. Fig. 3 is a side elevation of the crank-shaft, and Fig. 4 is a plan of a portion of the press with my improvement applied.

The machine is provided with a movable bed or beds having horizontal faces on which the type form rests, so that the paper can be printed on one or both sides.

Mechanism is provided for operating the bed or beds continuously, also an inking mechanism having a continuous rotary motion mounted on the reciprocating bed or beds and moving therewith. The inking mechanism is connected with the apparatus for operating the parts in such a manner that it will operate continu ously independently of the position of the beds.

The paper or other web material to-be printed is taken from a roll 10 over guide rollers 11, under a platen 12, over additional guide-rollers, and then under a platen 13, being printed on opposite sides when under the two platens.

In the operation of printing, a crank shaft 14 is ordinarily employed, this shaft having an arm 15 for raising and lowering the frame 16, carrying beds 17 and 18 I for operating against the platens 12 and 13 respectively. Located on the frame 16 and therefore moving with it, I have mounted bearings 19 for shafts 20, these shafts carrying sprocket wheels 21. Also located on this frame are a pair of shafts 22 which carry sprocket wheels 23, the latter sprocket wheels being loosely mounted on their shafts and turning independently thereof. The two sets of sprocket wheels are connected by chains 24 which carry an inking or ink applying device, I

inking rollers obviously are adapted to move over the surface of the beds 17 and 18, and also to travel around a pair of large inking rollers 26 which are keyed to the shafts 22, and consequently rotate with these shafts.

In order to rotate the large inking rollers in one direction and the chains in another, and to give rotation to these parts at all times when the shaft 14 is operating independently of the location of the beds, I have provided the following mechanism. On the shaft 14 is located a gear 27. With this gear meshes a gear 28 connected by gear 29 with a gear 30 on the lower shaft 20. This gear is connected by an intermediate gear 31 with a gear 32 on the upper shaft 20. The gears 28 and 29 are mounted in bearings on arms 33. pivotally mounted on the lower shaft 20, and adapted to fall by their own Weights sufficiently to keep the gear 28 in mesh with the gear 27 when the frame 16 rises and falls with the shaft 20. On the shaft 14 is also mounted another gear 34. This gear meshes with a gear 35 which is mounted in bearings on an arm 36 pivoted on the lower shaft 22 which carries a gear 37 meshing with the gear 35. The upper shaft 22 is operated from the gear 37 through an intermediate gear 38' and a gear 39 on the upper shaft 22. This part of the device operates in the same manner as the part on the other side, but the shaft 22 rotates in a direction opposite to that of the sprocket wheels thereon, which are driven from the shaft 20.

In order that gravity need not be depended upon for keeping the gears 35 and 28 in mesh with the gears 34 and 27 respectively, a pair of links 40 and 41 are employed to connect the concentric portion of the shaft 14 with the ends of the arms 36 and 33. In addition to these motions a crank rod 42-is connected with one of the shafts on the frame 16, this rod operating a bellcrank 43 which, through the instrumentality of a collar 44, reciprocates the shafts 22. I

It will be understood, of course, that ink is applied to the large inking rollers 26 in any desired way, as for example by means of ductor rollers 45 which are mounted to swing on shafts 46 as pivots, and are operated through connections 47 by a cam 48 on the shaft 14.

It is to be understood that while I have illustrated and described one particular embodiment of my invention, the same is not limited thereto in details of construction, as many modifications can be made by a person skilled in the art without departing from the scope of my invention as expressed in the claims.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent is:-
